To all whom it may concern:

Be it known that 1, JAMES" M Wins, a citizen of the Dominion of Canada, and

resident of Ottawa, in the county of Carleton and Province of Ontario, Dominion of Canada, have invented certain new anduseful Improvements in Devices for Supporting and Operating Lifting Jacks, of which the following is a specification.

This invention has relation to certain new and useful improvements in devices for supporting and operating lifting jacks and has for its primary object the provision of devices of the character stated which will be of' simple and compact construction, easy to manipulate and which will make it possible to operate the lifting jacks from a distance, thereby making it unnecessary to have the operator to be positioned close to the lifting jacks when they are placed under motor vehicles and the like.

Another object resides in the provision of a device of the character stated which may be employed in connection with various forms of lifting jacks and may be readily connected with the'lifting jacks or detached from the same and folded into compact form with the various parts of the device held against independent movement .when not in use. v

The invention has for a further object the provision of a device of the character stated which will be. constructed so as to rest securely on the ground or other surface with the operating rod and handle firmly supported in operative position during use of the device and the supporting portion of the device held firmly in position by the lifting jack resting thereon.

With the foregoing and other objects in view as will appear as the description proceeds, the invention consists in the novel con- I f portion 9 are pressed 111 so that when the struction, combination and arrangement 0 cooperating elements as hereinafter more nate corresponding parts throughout the sevv eral views, it will be seen that the device includes a pan or tray 5 to receive the base of the lifting jack 6 of conventional form. While the device may be employed in connection with any form of lifting jack desired, I have illustrated the device as being employed on a lifting jack of the form disclosed in my Canadian Patent 227,067 of December 12th,1922.

Extending from the pan or tray 5 is a supporting or base member 7 in the form of a channel bar and having a depressed portion 8 while the main part of the channel bar 7 is raised between the portion 8 thereof and the pan or tray 5. The channel bar 7 includes an inclined portion 9 extending'from the depressed portion 8 and connecting with the upwardly offset free end 10 which is flattened and bevelled or tapered toward its free extremity 11 so as to'serve as a tire removing tool, when required and as will be later understood. It is also to be noted from the drawings that a set screw 12 is extended through the upstanding flange 13 of the pan or tray 5 to secure the latter permanently on the base of the lifting jack A set screw 14 is extended through the upstanding flange. 15 of the channel bar 7, adjacent the pan or tray 5 and on one side of the channel bar 7, opposite and inwardly pressed extension 16 which is carried on the upstanding flange 15 at the other side of the channel bar 7. The purpose of the set screw 14 and the inwardly pressed extension 16 will later appear.

A standard 17 is pivoted at its lower end on the pivot pin 18 extended through the standard 17 is moved on the pivot pin 18 to upright position, the pressed in side flanges o the upstanding portion '9 will engage the flared lower end of the standard 17 and firml grip the same so as to retain the stan ard 17 in upright position. When the standard 17 is turned or swung forwardly and downwardly on the 18 to its lowermost position, the ower end of the standard 17 will be released and the upper or forward end thereof will be gripped by the inwardly grassed grl ping portions 19 of the upstan ivot pin ng side angea 15 of the channel bar 7. It is therefore apparent that the upper forward end of the standard 17 rests in the channel bar '7 when thestandard 1'7 is'in its lowermost or folded position. A ring 20 is,mounted on the pivot pin 20 carried in. the upper end of the standard 17 ande'x tended,transversely thereofii -such. a manner as to permit the ring 20 to. be supported on the upper end of the standard 17 as shown in Fig. 1 or move readily to a posith'n at an angle to the standards 17, as shown clearly in Fig. 3, as the'standard 17 is moved to its folded position. The operating rod 21 of the device is extended through the ring and provided on its forward end with-a suitable socket 22 to receive the end of the jack operating shaft 23. A set screw 29 is carried-by. the socket 22 to securely fasten the latter on the end of the jack operating shaft 23. An operating cross handle 25 is firmly fastened on the rear end of the operating rod 21. to serve as the means by'which the o crating rod 21 may be readily rotated in eitlier direction to operate the lifting jack 6. Handle grips 26 are carried on the end portions of the operating cross handle 25 and a suitable means is employed for re taining the operating cross handle 25 in proper position on the operating rod 21. This means may be in the form of a wing nut 27 as illustrated or in any other suitable form.

It is "believed the complete construction andv operation of the device may now be apparent from the foregoing paragraphs taken in connection with the accompanying draw ings Without further detail description. It

may be briefly stated, however, that when the device is not in use, the operating rod 21 is positioned in the chanel bar 7 with the socket 22 resting in the pan or tray 5 while the rear end portion of the operating rod 21 rests on the end portion 1001 the channel bar 7. The set screw 14 istightened against b the operating rod 21 to hold the same beneath the inwardly pressed extension 16, as shown clearly in Fig. 2. The device is then ready for transportation or for storage in a restricted space.

When it is desired to employ the device for supporting and operating lifting jacks, the set'screw 14 is loosened and the operating rod 21- moved to its horizontal or operative-position above the channel bar/7 and substantially parallel therewith. In moving the operating rod 21 .to this position the standard 17 assumes its right position, which position the standard .17 is firmly held by the inclined portion 9 of the channel bar 7 as previously stated in detail. It is thereoperative or upfore evident that a firm and solid support is provided for; the operatingrod 21 and after attachment of the socket 22 to the as shown in Fig. 1 and in 1 member to be operated of the lifting jack 6 or other device resting in the pan or tray 5, the operating rod 21 may be readily rotated in either direction by means of the operating cross handle 25. The pan or tray 5 should be firmly held in position by the set screw 12 .or other means provided for this purpose so as to securely lock the device with the member resting in the pan or tray 5. The depressed portion 8 of the channel bar 7 will rest firml'y on the surface on which the pan or tray 5 is placed even though the portionof the channel bar 7 between the. pan or' tray5 and the depressed portion 8 may not rest upon the surface. This will permit use of the device on uneven or stoney surfaces Without interfering with theefficiency of the device.

By forcing the operating rod 21 forwardly after the operating cross handle 25 is out of the way of the end portion 10 of the channel bar 7 and moving the standard 17 to its folded or inoperative position, the device may be employed as a tire remover. or replacer, owing to the formation ofthe end ortion 10. If desired, the wing-nut 27 may e removed and then the operating cross handle 25 withdrawn from the operating rod 21 and the latter removed from the ring 20 when employing the device as a tire remover or replacer or whenever it is desired to separate the parts of the device. 1

While the referred embodiment of the invention has een disclosed, it is to be understood that minor changes in the details of construction, combination and arrangement of co-operating elements maybe resorted to within the scope of what is claimed without departing from the spirit of the invention. a

What I claim as new is:
